The Bearded Fireworm can reach up to 35 cm in length. When disturbed, the marine annelid exposes beautiful tufts of white bristles. These bristles are hollow and venomous. They protect the worm from harm by penetrating the flesh of it’s attacker and detaching from the worms body.
During mating, females of the species will emit a green phosphorescent light. The males, noting the call, will quickly dash toward the source, emitting their own flashing lights. As the two grow closer, sex cells are shed and combined.
